I would like to learn to design amps + lay those on PCB so that
noise does not s those up. I have very poor analog skills, and
would like to improve those.

Apparently here the human noise pickup may make what seems
like Childs play to be a bit more than that, or how ...

I would be very interested, as my own design skills are
quite limited in this area, sadly so.

Would like to learn some most important practical hints how to
to be able to design something that do not radiate massively,
ok, I have Tim Williams books, that are not too bad, but to
be able to go trough it all and apply in practice has not been
as easy for me as it would have been when I was in better shape
healthwise. So, whatever I could learn, should be as easily
digestible as possible due to limited brain powers left.

I would like to be able to develop a UV detector that could be
used for 253.65 nanometer fluorescence/absorbance detection
combined with fluorescence and/or absorbance cell, and want
to get to the same level of performance at least as the
past photon amplifier tube based designs, I am targeting moderate
performance for low cost, not the high end performance for high
end cost like the usual instruments out there, I would like to
be able to help the poor third world to detect environmental
poison without the usual first world budget.

If you can put up with the fact, that I suffer from quite
severe jaw-bone/skull aches, that come from chronic jaw bone
infection, which pains reflect on my writings ,I would really want to
learn more, of the analog design area,and the EMI/EMC area, that are
my weakest links, in addition to being relict in the software arena,
can get embedded code working fast, but PC side coding is painful and
no linux skills.

Wasn't the Binaural sound hardware and the software your
achievement, I am very interested of that,too, and wonder if my
diminished thinking speed and concentration could be helped
with the "UP" function, I would be very much interested of that,
too, and of chance to try the UP sounds.

I know for a fact that different types of beats have quite
an effect on humand mind, so, I would really want to try the
binaural beats/ up frequency tunes.

Thank You, Sade M.
